[0019] Example
[0020] A small vacuum magnetron three-target sputtering plating machine, including a vacuum chamber 3, an upper cover of the vacuum chamber 2, three magnetron targets 1 evenly distributed on the upper cover 2, in order to offset the gravity when the upper cover 2 is opened , The upper cover 2 is connected with two pneumatic support rods 5, the front of the vacuum chamber 3 is provided with a glass observation window 4, the right side of the vacuum chamber 3 is provided with an auxiliary lighting interface 17, and the exhaust port at the rear of the vacuum chamber 2 is provided with a throttle Valve 13, changing the angle of the throttle valve 13 changes the size of the air flow into the molecular pump 11, which plays a role in adjusting the vacuum degree, and can also block a part of the sputtered substance from entering the molecular pump 11, thereby extending the molecular pump 11 Service life. The pumping port of the molecular pump 11 is connected to the pump...
